    In our case it was Network Policy Server.

    lockoutstatus.exe identified the DC which had locked the account.
    4740 events showed the Caller Computer Name to be blank.
    Windows -> Security log on the NPS showed failed logon attempts with the same timestamp as the lockout.

    Hi,
    This worked for me. What is the default logging though. How do I set it nltest back to normal?
    Nltest /DBFlag:2080FFFF
    And run below commands to restart netlogon Service
    net stop netlogon
    net start netlogon

    Thanks

    Hi,
    I should’ve clarified Windows 2012 R2 SP1 environment.
